Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is.

For decades, quantum computers that perform calculations millions of times faster than conventional computers have remained a tantalizing yet distant goal. However, a new breakthrough in quantum ...

A new study has uncovered important behavior in the flow of electric current through quantum superconductors, potentially advancing the development of future technologies like quantum computing. In a ...

The strange connections between quantum objects are the strongest relationships physicists can detect – and the mathematics of graphs may help explain why that is. Quantum objects can be connected, or ...

Quantum technologies are radically transforming our understanding of the universe. One emerging technology are macroscopic mechanical oscillators, devices that are vital in quartz watches, mobile ...

We may never beam ourselves off the planet. But quantum teleportation is poised to bring about a new era of computing—and revolutionize our understanding of the subatomic world. This composite photo ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...
